Terminologies in Introduction to Pharmacology Flashcards
It is the scientific study of the origin, nature, chemistry, effects, and uses of drugs.
Pharmacology
It is the absorption, distribution, metabolism, and excretion of drugs by the body
pharmacokinetics
It is the biochemical and physical effects of drugs and the mechanisms of drug actions
pharmacodynamics
It is the use of drugs to prevent and treat diseases. In addition, it discusses other important aspects of pharmacology, including:
• how drugs are named and classified
• how drugs are derived
• how drugs are administered
pharmacotherapeutics
It is a scientific name that precisely describes the drug’s atomic and molecular structure.
The chemical name
It is an abbreviation of the chemical name.
The generic name or nonproprietary name
It is selected by the drug company selling the product. This names are protected by copyright. The symbol ® after a the name indicates that the name is registered by and restricted to the drug manufacturer.
The trade name (also known as the brand name or proprietary name)
It is a route that allows direct drug administration into the GI system. It is used when patients can’t ingest the drug orally. This route is accessed through a tube placed directly into the GI system, such as a “G-tube.”
gastric route
It is an administration of drugs that are injected into the skin. A needle is inserted at a 10- to 15-degree angle to puncture only the skin’s surface. This administration is used mainly for diagnostic purposes, such as testing for allergies or tuberculosis.
Intradermal administration
It is a route that allows drugs to be injected directly into various muscle groups at varying tissue depths. This form of administration provides rapid systemic action and allows for absorption of relatively large doses (up to 3 mL).
Intramuscular route
It is a route that injects drugs and other substances directly into the bloodstream through a vein. Appropriate substances to administer here include drugs, fluids, blood or blood products, and diagnostic contrast agents.
Intravenous route
It is usually the safest, most convenient, and least expensive route. Oral drugs are administered to patients who are conscious and able to swallow.
Oral administration
Drugs that are available as gases can be administered into the respiratory system through inhalation. These drugs are rapidly absorbed.
Inhaled route
An administration of small amounts of a drug are injected beneath the dermis and into the subcutaneous tissue, usually in the patient’s upper arm, thigh, or abdomen. This allows the drug to move into the bloodstream more rapidly than if given by mouth.
subcutaneous (subcut) administration
It involves collecting data that are used to identify the patient’s actual and potential health needs. You can obtain data by taking a health history, performing a physical examination, and reviewing pertinent laboratory and diagnostic information.
